Control method and system for forest fire exploration through unmanned plane

Abstract

The embodiment of the invention discloses a control method and system for the forest fire exploration through an unmanned plane. The method comprises the steps: obtaining a fusion image and the brightness temperature values of all pixels in the fusion image through the preprocessing, splicing and fusion and brightness temperature inversion of a visible image, a short-wave infrared image, a mid-wave infrared image and a long-wave infrared image; recognizing the position of an open fire point and the position of a blind fire point according to the fusion image and the brightness temperature values of all pixels in the fusion image; finally analyzing the influence scope of forest fire and the distance between the center of the forest fire and a power transmission line according to the positions of the fire points, determining the level of forest fire, and carrying out the early warning according to the level of forest fire. Compared with the prior art, the method can effectively distinguish the open fire point and the blind fire point, can carry out the early warning timely according to the level of forest fire, can effectively improve the detection rate of the forest fire and the put-out success rate of the forest fire, reduces the safety risk of fire fighters, and guarantees the safe and reliable operation of power transmission lines.

Description

technical field [0001] The invention relates to the field of electrical geological exploration, in particular to a control method and system for unmanned aerial vehicle mountain fire exploration. Background technique [0002] Generally speaking, wildfires can be divided into open fires and dark fires. Open fire usually has obvious flame (flame) rising, violent reaction, strong heat radiation, and the firefighters are more dangerous when fighting. Dark fires often have no flame, commonly known as smoldering, similar to the burning of cigarettes, especially difficult to judge whether they have been completely burned, and dark fires are easy to re-ignite, so it is more difficult to fight dark fires, and the losses caused by dark fires are also greater . The high mountains and densely forested power transmission corridors in my country objectively determine the possibility of frequent wildfires in dry seasons with little rain. [0003] Many transmission lines in my country ar...

Problems solved by technology

[0005] An embodiment of the present invention provides a method and system for controlling wildfires by UAVs to solve the problems in the prior art that it is difficult to distinguish between open fires and dark fires when using UAVs to explore mountain fires in transmission line corridors and to control mountain fires. The problem that the fire image range cannot make a reasonable assessment of the disaster situation
